It is possible you attempted an upgrade while cygwin programs were running? Cygwin services also count. This is due a limitation on windows which locks files when they are in use, so cygwin updates can't replace the files and end up failing. You may ensure everything is closed and services stopped, re-run setup-x86_64.exe, selecting the 'nc' package and switching it to "Reinstall". Then let the setup do its things. If the setup is hanging, or have hung up and you had to force-close it the last install attempt you did, this is a strong sign that not just nc, but several other packages that have been attempted to upgrade may be compromised. To ensure that is not the case, a good cygcheck -c should help. The package nc-1.10-4.tar.bz2 has 'usr/bin/nc.exe', which is the file you claim missing.

I have notes that show what all I need to shut down when doing the install. I caught all them (Cygwin SSHD, Cygwin cygserver, the X Server, and anything running cygwin shells, etc.) - I think that's everything. When I run cygcheck -c, it shows Incomplete on the two packages (nc and nc6) so they definitely had problems, and appear to be the only ones which did.

This ensures short paths and I can 'ls /packages' to fiddle with them. I wouldn't advise you to just go ahead and unpack the packages. Cygwin setup runs some shady things when it installs packages (aka rebaseall) in order to settle usable memory for the installed tools (another unfortunate limitation of cygwin due to windows design). I see that you are relying on cygsetup so that shouldn't be the problem, just making sure. You can set up this packages directory when you start cygwin setup. It is one of the first questions it makes. I believe it would be wise to manually move that packages directory to where you want it before so that cygwin just finds whatever it installed still in place after you specify the new path. This might solve the long path, although I don't think this should be the problem... Cygwin supports quite long paths as far as I know, or believe. :) I don't think the '.xz' extension has anything to do with the issue, it is just the compression protocol the files follow. On another topic, if you just chose to reinstall the "incomplete" packages only, why the hell did setup want to fiddle with that other package you named (libfm-...)?.. Perhaps you need first to switch the "latest" to "keep" (in the packages selection phase of setup) so that it does not try to upgrade everything else and just reinstalls the packages you specified. Once nc and the incomplete packages works you may give the full upgrade a try. You can just hit 'back' once it completes installation and do the upgrade steps (instead of closing and re-opening the cygwin setup application). Well, I hope this helps! :) On 7/11/2018 4:45 PM, Mark Hansen wrote: > On 7/11/2018 12:34 PM, Mark Hansen wrote: >> On 7/11/2018 10:34 AM, Heavenly Avenger wrote: >>> I have these versions, and nc is here happy and playful. >>> >>> It is possible you attempted an upgrade while cygwin programs were >>> running?

Yep. If you're in a corporate environment, IT may have a program running to check for the installation of unwanted and suspicious files. Corporate IT departments do not like Netcat.

I think I solved it by either renaming nc.exe to something else, compiling my own Netcat, or using Socat, but I don't remember which approach actually worked. And of course, depending on the company and the IT department, you may want to consider whether using the program in spite of their efforts to prevent you from doing so is worth the risk of termination.

I do, and did without issue after explaining the business case to my It department. (if fact, they gave me admin to configuring the antivirus on my machine rather than just the netcat exception). If you don't have a business case for having netcat on your work machine, I'd highly recommend removing the install packages too, as 'a fun toy' is not a good reason to get fired. -- Erik -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple ^ permalink raw reply [flat|nested] 15+ messages in thread
